IMPROVEMENT IN STRlPPER-CARRYlNG FRAMES FOR CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 115,185, dated May 23,1871.

To all whom it may concern:

Be it known that I, JOHN F. Foss, of Low Massachusetts, have inventedcertain new and useful Improvements in OardStripping Ma= chinery, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing making part of this specification,in which--- 7 Figure 1 represents a transverse sectional elevationthrough the center of the main cylinder. Fig. 2 is an end view, and Fig.3a detached section of a portion of an ordinary mangle-motion, showingseveral of the pins and the operating-pinion.

This invention relates to certain improvements in the machinery orapparatus which is used for stripping the flat tops of cardingmachines,and to that of the apparatus which carries the lifting and strippingmechanisms.

struction of the stripper-carrying arms or frame-work, and in the modeor means of applying the latterto the main cylinder-shaft, whereby thetraversing of the arms or framework is performed by a single traversingmechanism at one end of the machine, thereby saving considerable in thecost of the apparatus.

In the said drawing, A represents the cylinder, arranged on a centralshaft, B, and supported in boxes or bearings (J, on the frame D, asusual. The stripper-carrying arms E are constructed each with anoffset,'g, a shaftreceiving hub or plate, f, and lower dependin gextremities I, which extend below the cylinder, where they are firmlyconnected by a cross bar, H, and this crossbar maybe of sufficientspecific gravity to serve as a counterbalance, and thereby partially orwholly overcome the action of the load upon the upper portion of thearms. This lower crossbar placed a suitable distance below thecardteethon the main cylinder, say from one to light waste and fibers ofcotton which accu mulate beneath the cylinder, by crowding such wastesubstance away from beneath the cylinder and off at the sides of themachine at each forward and backward traverse or 0s cillation of thebar. A secondv crossbar G,

is firmly secured to the tops of the strippercarrying arms E, and this,with the arms and thelower crossbar, constitutes a rigid and substantialframe-work capable of being operated, traversed, or oscillated from oneside of the machine to the other by a single traversing mechanism, whichmay be any of the wellknown devices used for that purpose.

" In the present instance I have shown a very common traversingapparatus, consisting of a curved row of pins arranged beneath thecard-arch, and a pinion-gear, c, which operates on all the stationarypins around both end pins, and on either side of all of them. Any othercommon traversing device may be employed in connection with my saidimprovement, and such traversing device will only be required on one endof the card, which saves in the cost of the apparatus.

It willbe observed that the arms E are carried close to the ribs K, ortop flanges of the arches, and that the ofl'set in each arm carries theshaft-receiving hub and the depend ing lower extremities of the armsinside of the frame-work.

This construction and arrangement of the arms is designed for a twofoldpurpose: First, to furnish means for applying the lower crossbar; andsecond, to allow the pulleys on the main cylinder-shaft to be carriednearer the frame-work or end of the machine, and thereby economize inroom or space by bringing the carcls nearer together, which enables meto add at least one card to each row or set of cards in a room orsection, thereby increasing the carding capacity of the section, room,or mill.

In Fig. 1 I have shown a top flat, M, (so called,) in its commonposition above the arches, with card-teeth e on the top flat, and alsoon the cylinder, to show the relative position of the parts.

I claim as my invention- 1. The stripper-carrying arms E, constructed asdescribed, each with an ofiset, g, a shaftreceiving hub or plate, f, andadepending lower portion, I, arranged within the framework, whereby thelower cross-bar H can be applied in the manner and for the purposedescribed.

2. The strippcr'carrying arms, constructed as: described, in combinationwith and connected. by cross-bars H and G, all constitutarranged betweenthe end frames D, for the purpose and in the manner substantially as inga frame-work capable of being traversed described. or oscillated fromone side of the card to the other by a single traversing mechanism,substantially as described.

3. The lower cross-bar H, in combination .with and carried by thedepending arms 1,
